Modeling and Realization of a 24-GHz FMCW Radar for Accurate Target Distance Identification

In this work, the modeling and realization of a 24-GHz Radar based on the BGT24MTR11 chipset is presented. The model has been implemented with the Visual System Simulator (VSS) tool available inside the AWR software. Two modular implementations of the designed Radar have been proposed. One in which the Radar is driven by a DAQ card from National Instruments and one in which the Radar is controlled by a PLL circuit. The circuit model has been validated through a comparison with analytical and experimental measurements considering as target a metallic sphere. The better performance of the architecture with the PLL has been also evidenced by considering a scenario with a panel target.
